摘要：路燈是每個城市不可或缺的必需品，隨著我國改善人民生活條件、建設小康社會及提高勞動生產水平等目標的實現，對路燈供電質量的要求也越來越高。近年來各地政府都十分重視城市光亮工作，把城市照明設施建設作為改善和美化城市環境的重要措施。讓城市亮起來、美起來，已成為社會各界的共同認識。同時，路燈的供電質量也要保證。本文從路燈的系統的介紹了路燈供配電中的一些常見問題，介紹了路燈材料的選取，電纜的選擇、變壓器型號的選擇及其它的配套設施，介紹了無功功率的補償方法。最后還對比幾種不同的節能、控制方法，選出了最優化方案。

Abstract：The street light is indispensable to each city, along with improving the living conditions in China. building a moderately prosperous society and to improve labor productivity level goals, the increasingly high requirements on the quality of street lamps powered. In recent years, local governments have attached great importance to the city light work, the construction of urban lighting as an important measure to improve and beautify the urban environment. The city lights up, America has become a common understanding of the community. At the same time, the street lamp power quality should be guaranteed. This article from the street light system introduced some common problems in the street supply and distribution, street light materials selected, the choice of cable, transformer model selection and other supporting facilities, the reactive power compensation. Finally, comparison of several different energy-saving control method elected by the optimization program.　

Keywords ：power supply and distribution；streetlight;ballast; the compensation of reactive power

　　　本設計詳細對比和介紹了路燈照明中的無功功率和無功功率補償方法，路燈配電系統中電力電纜的選擇，以及變壓器的選擇和保護等幾個方面。在我國目前的路燈配電系統中，較為有有優勢的無功功率補償方法為分散補償法，即單燈補償。在路燈照明中，還應考慮路燈照明的穩定性，即路燈應保持正常的工作狀態，因此，路燈的控制系統就顯得至關重要，本設計詳細介紹和對比了路燈幾種控制方案，選取了比較有優勢的方案設計。

　　　本設計的目的，就是為了路燈照明供電系統的安全、穩定、節能和可靠。在城市化進程告訴發展的今天，本設計對路燈照明系統供配電有著一定的知道意義個參考價值。
